Introduction
I.
Introduction
The FBT-10 provides a convenient, portable platform for
everything needed to commission a Fieldbus segment. This is
accomplished with or without mains power, and with or without a
Host (DCS). Commissioning can then begin at an earlier stage in
the project. Sockets in the FBT-10 provide a convenient way to
connect, store, and transport Fieldbus diagnostic tools such as
the FBT-6, F809F, FBT-9 and FBT-11 (please see literature on
these tools for more information on their features). The unit is
rugged enough to be shipped to site or checked onboard an
airplane.

Operation
Master Power Switch
This illuminated switch enables power to all functions on the
Commissioning Box except for battery charging. It is recessed to
prevent accidental activation. The Master Power Switch should
be OFF when not using the Commissioning Box to prevent
draining the battery.
FBT-9, F809F, and FBT-6 Switches
These three switches enable power to the FBT-9, F809F, and
FBT-6 respectively. They are not illuminated because the FBT9, F809F, and FBT-6 themselves indicate when they are
powered.
Light Switch
Four (4) white LEDs in the upper corners of the
case lid are illuminated when this switch is ON.
These LEDs will provide light for the Panel
when there is not enough ambient light.
Shield Ground Switch
When this switch is ON, a relay inside the
Commissioning Box connects the Segment
Shield to the Ground Terminal (next to the
Mains Power Connector). Note that the Panel,
Ground Terminal, and Mains Ground Terminal are all connected
together internally. The purpose of this switch is to provide an
easy way to ground the Segment Shield if it is not already
502-940 FBT-10 User Manual Rev A.0

Operation
grounded. If this is what is desired, an earth or plant ground
connection through the Mains Connector or Ground Terminal is
required.
FB Power Supply
If there is already power on the Segment, the FB
Power Supply Switch should NOT BE TURNED ON.
If power for the Segment is not already available, this switch may
be turned ON to provide power to the Segment. The switch will
illuminate and the Green LEDs above the two Trunk Connectors
will also come ON. The Green LEDs above the two (2) Trunk
Connectors indicate Segment power regardless of the source.
Notice that when switched ON, a Terminator is also connected to
the Segment.
Terminator
This switch illuminates when turned ON and provides a
Terminator on the Segment. It should only be used if another
Terminator is needed on the Segment. Fieldbus requires two (2)
Terminators on a Segment. Normally one is included in the
Fieldbus Power Supply and the other near or part of the Fieldbus
Device Coupler (Megablock).
FBT-9, FBT-6 Slots
These two slots are
made to connect and
hold an FBT-9 or
FBT-6 to the
Commissioning Box
without using any
cables. Relcom may
also make other
instruments in the
future that fit these
slots. For example, the FBT-11 will fit in the FBT-6 slot. To
install the instrument, loosen the two screws fixing the Holder to
8
502-940 FBT-10 User Manual Rev A.0
Operation
the Panel. Insert the instrument lining up the pins and sockets.
Replace the Holder to secure the FBT device. In the figure
above, the FBT-9 instrument is installed and the FBT-6 Holder
has been removed and moved up to show the holder mounting
holes.
Please see our website for information on the FBT-6, FBT-9, and
FBT-11 (www.relcominc.com).
F809F Slot
An F809F may be inserted into the long, narrow slot in the
middle of the Panel. The “F809F” part number on the F809F
label should be toward the top of the Panel. Two screws hold
the F809F in place. Tighten them to keep it secured.
The F809F is a Fieldbus diagnostic product made by MTL.
Please see their website for more information (www.mtlinst.com).
Diagnostic Segment
When using the F809F, this connector is where a Host would
connect to retrieve the diagnostic information about the Segment
under test from the F809F. It is connected to Segment 8 on the
F809F. The Commissioning box provides limited (1 device)
power and two (2) Terminators for this Diagnostic Segment.
Segment 2 on the F809F is connected to the Segment under
test. The jumper on the F809F must be set to report its
diagnostics on Segment 8. If you need to connect the F809F to
a powered segment do not use the Diagnostic Segment
Connector. Instead connect the segment directly to the
connector on top of the F809F. The Fault LED above the
connector will illuminate (red) if too much load (>40mA) is
connected to this connector. See the F809F documentation at
www.mtl-inst.com for more information on the F809F.

Operation
Field and Host Trunk Connectors
These two connectors provide access to the Trunk for the
Segment being tested or configured. Above each connector is a
Green LED to indicate whether there is power on the Segment.
The names “Field” and “Host” are somewhat arbitrary, but can be
helpful to keep cables identified during testing. For example, the
Field Trunk could be connected to a cable that goes to a skid
while the Host Trunk would be connected to a temporary Host
such as the Emerson 375/475 or the National Instruments
Configurator.
Device Connections
The four (4) gray connectors are current limited (short circuit
protected) connections to the Segment under test. A red LED
above the connector illuminates if the associated connection is
overloaded or shorted – see the Specification section for ratings.
These connections are typically used to connect Fieldbus
Devices to the Segment under test.
Scope Connection
Two pins in the Panel provide access to the Trunk of the
Segment under test for an oscilloscope connection. CAUTION:
shorting these two pins together will short the entire Segment
under test.
Ground Terminal
This terminal may be used to ground the FBT-10 to a local earth
ground. This would be desirable if the Shield for the Segment
under test needed to be grounded. The FBT-10 can connect the
Shield for the Segment under test to the Ground Terminal using
the Shield Ground Switch (page 7).

Operation
Battery Status
This is an LED bar graph that indicates the
battery voltage. Only one LED is on at a time to
indicate the current battery state. When the
battery voltage falls below the lowest LED
position, the LED will begin to blink at a slow rate.
Charger Status
These two LEDs indicate the Status of the
internal battery charger. Mains Power must be
supplied to the FBT-10 for the charger to work. If
the Charger Status LEDs are OFF and the AC
Power LED is ON, then the battery is being trickle charged – it is
fully charged. If one or both of the Charger Status LEDs are ON
the battery is being fast charged.
Mains Connector
This connector is used to provide Mains power to the FBT-10.
When Mains power is being supplied to the FBT-10, the Green
AC Power LED will be illuminated and the internal battery will
charge. If the Mains power cable is grounded to a local ground,
then the FBT-10 will also be grounded (including the Ground
Terminal).
20-30VDC Output
This two (2) pin connector may be used to
supply power to other devices the user may
need to power. A Red Fault LED illuminates if
the output is shorted or trying to draw too much
current. The output voltage will depend on the battery voltage or
will be near 30VDC if the FBT-10 is connected to Mains power.
502-940 FBT-10 User Manual Rev A.0

Operation
Shield Grounded LED
An internal detector monitors the Shield for the Segment under
test and illuminates this Green LED when the Ground Terminal
and the Shield are connected together. Note that when the
F809F is being used (is powered ON) and the Shield is
grounded, this Green LED may blink. This is considered normal.
FB PS Fault LED
This Red LED indicates when there is a fault with the internal FB
Power Supply (when it is being used). A solid Red LED
indicates that the Segment under test is drawing too much
current or is shorted. A blinking LED means that an internal fault
has occurred with the FB Power Supply. If this happens,
arrange to have the unit serviced at the factory.

Use Cases
IV. Use Cases
In this section, some example use cases for the FBT-10 will be
covered.
Pre-Commissioning
In order to configure a Fieldbus device, a working segment
including a Host must be connected to it. With a portable Host
and the device to configure connected to the FBT-10,
communication can be established and the device configuration
can be completed. The battery in the FBT-10 supports precommissioning anywhere - in the field, on a truck or barge, in a
maintenance shop, etc.
Training
A complete Fieldbus segment on a table can be achieved by
connecting a Fieldbus Device and Host to the FBT-10. This can
be invaluable for demonstrations or training of personnel.
Adding the F809F or FBT-6 diagnostic tools allows trainees to
see diagnostic results from segments that are operating well and
those that are not (when inducing disturbances with the FBT-11).
The diagram above illustrates how little is required to conduct
pre-commissioning or training when using the FBT-10.
Depending on the type of training required, the FBT-9 could be
used instead of a 375/475 or NI Configurator.
502-940 FBT-10 User Manual Rev A.0
13
Use Cases
Skid Validation
A skid will typically have several Fieldbus devices and a
Terminator. A Fieldbus Power Supply, Terminator and Host must
be connected to the skid segment to test its operation. The FBT10 contains everything to accomplish this except for the Host.
Attach a portable host, such as a laptop with a National
Instruments Fieldbus interface or an Emerson 375/475, and
validation may begin. If Fieldbus device configuration/exercise is
not required, an FBT-9 may be used instead of a portable Host.
The FBT-9 is a simulated Host that will establish communication
with all Fieldbus devices on the segment. See the FBT-9 product
specification on our website (www.relcominc.com) for more
information.
Segment Checkout
The FBT-10 facilitates testing a segment before it is fully
complete. If the Fieldbus Power Supply is not yet online, the
FBT-10 can supply power to the segment. It also provides
sockets for diagnostic equipment. The FBT-6 or F809F can be
used to monitor the health of the segment. The FBT-9 simulates
a Host to establish communication among the Fieldbus devices.
Using an FBT-11, the resilience of the segment can be tested.
The segment’s robustness is measured by how well it will
tolerate the adjustable disturbances imposed by the FBT-11. See
the FBT-11 product specification for more information.
In the above diagram, the Device Coupler and Fieldbus devices
are either located on a Skid, or in the field. A 375/475 or NI
Configurator is shown, but depending on the requirements, an
FBT-9 docked to the FBT-10 may be used instead.

502-940 FBT-10 User Manual Rev A.0
Battery Management
V.
Battery Management
The FBT-10 uses two (2) 12VDC, 8Ah Sealed Lead Acid (SLA)
batteries to power the unit when Mains power is not available. It
also contains a battery charger which charges the battery
whenever Mains power is connected (whether the unit is ON or
not) as well as a protection circuit to prevent discharging the
battery too far.
SLA batteries like most batteries have peculiar characteristics
that are worth understanding to prolong the battery life.
Discharging a battery too far will shorten its life.
Although temperature dependent the self-discharge rate of a
SLA battery is about 3% per month. If the FBT-10 is stored for a
long period of time, it is possible that the battery may discharge
below the recommended minimum and the battery life will be
significantly diminished. Recommendations for increased battery
life are:
1. Store at 20°C or less.
2. Recharge after each use.
3. Recharge at least annually if not in use.
Master Power Switch Accidently Left On
When the unit is ON circuitry monitors the battery voltage
continuously. If the voltage gets too low (about 21VDC), all
functions are shut down except for the monitoring circuitry. If the
unit stays in this mode for about an hour, it completely shuts
down – just as if the Master Power Switch was turned OFF.
This situation may cause confusion because the Master Power
Switch will be ON, but nothing will indicate that there is power to
the unit. To reset from this condition, turn the Master Power
Switch OFF and then back ON. The unit needs to be adequately
charged to function properly when using battery power.

Service
VII. Service
The Commissioning Box does not contain any user serviceable
parts. All adjustments and/or repairs have to be performed at
the factory. If the Commissioning Box needs to be serviced,
contact Relcom for return instructions. If the Commissioning Box
is still covered by the limited warranty, the repairs or replacement
will be made free of charge. For service outside the warranty,
contact Relcom to determine the charges for the service before
sending the unit back to the factory.
VIII. Shipping and Air Travel
The batteries in the FBT-10 are considered a “Non-spillable
Sealed Lead-Acid Battery” and as such are able to be shipped
and transported on airlines as checked luggage. The batteries
themselves are marked similar to the following (although the way
they are mounted in the FBT-10 it would be difficult to read them:
“Classified DOT Class 60 dry cell. Meets air transportation
requirements for transport under title 49CFR173.169 and special
provision A67 as decreed by IATA and ICAO.”
To facilitate airport inspection by agencies such as TSA, there is
a sticker inside the case lid with instructions for opening the
Panel so the Airport Inspector can verify what is under the panel.
This is required because the batteries look like big black bricks to
their X-ray machine. We have traveled with the unit as checked
baggage with no issues.
